Maybe the patch description is off. All this does (in a very non-sexy way) is set ai_src_addr. It does not allocate any hardware resources. A user can provide ai_src_addr as input into rdma_bind or rdma_resolve_addr. The motivation is twofold. First, the user can select the rdma_addrinfo for a connection by examining the src/dst address pair. This may be desired for failover or performance reasons. Second, route resolution may require knowing both the source and destination addresses. For example, IB ACM requires both addresses as input. - Sean -- To unsubscribe from this list: send the line "unsubscribe linux-rdma" in the body of a message to [email protected] More majordomo info at http://vger.kernel.org/majordomo-info.html
